What’s wrong with supply and demand?

It’s a tautology with no causal or explanatory power

Supply and demand is the bread and butter of mainstream economics discourse. Economists love to take reality, and simplify it into to some rule or pattern, that allows them to avoid discussing or addressing many real and complex issues.

This is the reason for the emphasis on empiricism. It is not sufficient to note the realities of accounting and resource decisions, but rather, some abstract quantitative rules must be discovered, which allow you to ignore reality and just focus on the numerical patterns. I will call this abstraction replacement. When your goal is for the abstraction to replace reality, rather than helping you analyze it.

This is the reason for such an emphasis on (unrealistic) mathematical models. Mainstream economists don’t want reality to creep in on their analysis, so they create these toy models. There would be nothing wrong with these models in and of themselves, except they are not fully or adequately acknowledged as such.

Artificial Isolation of Concerns

So when it comes to supply and demand, the issue is what I call “artificial isolation of concerns”

Production is considered separately from property rights, which is considered distinct from consumption and income, and government policy. Everything is divided into neat little buckets. Then we can put the problems into one bucket or another.
